EMERGENCY-SHOE.

Specification of Letters Patent.

Patented Sept. 28, 1915.

Application filed November 27, 1914. Serial No. 874,246.

To all whom it may concern Be it known that I, FERNAND E. RIVIERE,

a citizen of the United States, residing at tween the periphery of thewheel and the track; and another object of the invention is to improvethe construction of the shoe.

The invention aims to improve generally and to enhance the utility ofdevices of that type to which the present invention appertams.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made withi in thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawing: Figure 1 is a view partly in section andpartly in elevation showing a railroad car equipped with the brakemechanism forming the subject matter of this application; Fig. 2 is atop plan of the brake mechanism; Fig. 3 is a side elevation of the shoe;Fig. 4 is an elevation showing one edge of the shoe; Fig. 5

is a top plan of the shoe; Fig. 6 is a pertail illustrating one of theguides or hangers in which the shoe actuating plunger is mounted; Fig. 9is a fragmental side elevation showing the position of the shoe andadjacent parts when the shoe coacts with the wheel.

In the drawings, the numeral 1 indicates generally a vehicleof anydesired type, such as a trolley or railroad car.

The wheels of the car 1 are denoted by the numeral 2 and the rim of thewheel is indicated bythe reference character 43.

- The track which is traversed by the wheels of the car is shown at 3.

The numeral 4 indicates the truck frame and carries axles 5 upon whichthe wheels 2 are immediately mounted.

The platform of the car is shown at 6.

Mounted upon some accessible portion of the car, as in the platform 6,is a base plate 7 equipped with an upstanding ear 8 carrying a pivotelement 9 upon which is fulcrumed .a lever 10 extended downwardlythrough the platform 6, the lever 10 being provided with suitable latchmechanism of any desired sort indicated at 11 and adapted to coact witha segment 12 which if desired may be fixed to the base plate 7. Securedto the lower end of the lever 10 and to the car is a retractile springwhich serves toprevent too abrupt a throwingof the lever 10 and alsoaids in returning the parts to the positions shown in Fig. 1.

Pivotally connected with the lower end of the lever 10 as shown at 14 isa rearwar'dly extended pitman 15, mounted to reciprocate in a guide 16carried by the platform 6. The rear end of the pitman15 is upwardlyinclined to form an arm 17 pivotally connected as shown at 17 with anupstanding crank arm 18 on a shaft 19 journaled for rotation in bearings20 carried by any accessible portion of the frame of the car 1.Projecting downwardly from the shaft 19 is an arm 21 to which is pivotedas shown at 21, a downwardly and rearwardly extended plunger 22. Theplunger 22 at its rear end is formed into a goose neck 24 receivedwithin a guide 28 depending from the truck frame 4. When the parts arenot in operation, as shown in Fig. 1, the goose neck 24 rests upon thelower portion of a loopshaped head 51 constituting a part of the guide23. The plunger 22 is mounted to move vertically in the loop-shaped head51 of the guide 23 but cannot rotate or move laterally, as Fig. 8 willmake evident. The goose neck 24 terminates in a curved finger 52 and tothe goose neck are pivoted links 53.

The invention includes a shoe 25 provided near its upper end with anopening 26 receivlng a pivot element 27 which 1s connected to the links53. In the shoe 25 at its upper end is formed anopening 28 adapted toreceive the lower end of a chain 29 constituting a part of alongitudinally entensible, resilient connection. The upper end of thechain 29 is assembled with the bend of a U-shaped link 30 provided atits upper end with hooks 31. A compression spring'32 surrounds theU-shaped link 36 and the upper-end of the spring 32 is engaged by thehooks 31. The lower end of the spring 32 is engaged by a cross pin 33mounted in an eye 34 formed at the lower end of a link 35, the upper endof which is connected with a chain 36, the upper end of the'chain 36being connected as shown at 37 with the truck frame 4. 1

Theforward edge face of the shoe 25 is convexed as shown at 38 and therear edge face of the shoe 25 is concaved as shown at 39 toconformproperly to the periphery of the wheel 2. The faces 38 and 39cooperate to define an entering point 40 which, when the device'isoperated, is adapted to move between the periphery of the wheel'2 andthe track- 3. The forward edge face of the shoe 25 is a friction face,and with this end in .view, the said face may be grooved or ribbedtransversely as shown at 41. The rear, concaved edge 39 of the shoewhich coacts with the periphery of the wheel 2 is grooved longitudinallyas shown at 42 so as to receive the rim 43 of the wheel 2. EX-

tended outwardly from the friction face of the shoe 25 is a rib 44whichis adapted to engage the inner edge of the track 3'when' the deviceis in operation, and owing to the coiiperation betweenthe rib and thetrack 3 upon the one hand and between the groove 42 and the rim 43 ofthe wheel 2 upon the other hand, a movement of the shoe in a lateral ortransverse direction is avoided.

l/Vhen the structureis not in use, as shown in Fig. 1, the shoe 25 isretracted-from the periphery of thewheel 2. The goose neck 24 of theplunger'22 is supported upon the lower portion of the head 51 of theguide 23,

and thus the shoe 25 is upheld, the lower.

chain 29 of the longitudinally extensible connection hanging slack.

In order to operate the structure, the pit; man15 is actuated throughthemedium of.

track. The longitudinally extensible 0011- the shoe and supports theshoe in position.

When the shoe 25 enters between the wheel. 2 and the rail 3, the shoe istilted, and'when the shoe is thustilted, the goose neck 24 in theplunger 22receives the upper end of the shoe andprevents the plunger 22from being strained by direct contact between the upper end of theshoe-and the plunger. The shoe 25 may be-ra-ised into the position shownin Fig. 1 by a proper manipulation attendant parts being facilitated bythe action of the spring 32 and'the .spring 50.

of the lever 10, the raisingof the shoe. and

Having thus described the invention, what I is claimed is 1. In a deviceof the class described, a wheel mounted vehicle; a fixed, dependingguide thereon; an inclined plunger mounted to move longitudinallythrough the guide in direct contact therewith; awheel engaging shoepivoted to the plunger; and means for advancing the plunger to lower theshoe; the plunger being provided with means ene gaging the shoe topreventa movementof the shoe in one direction with respect to theplunger, thereby to hold the shoe against tilting with respect to thewheel, when the shoe is elevated.

2. In a device of the class described, a]

wheel mounted. vehicle; a plunger carried thereby; means for actuatingthe plunger; I

and a wheeland' track-engaging shoe pivotally assembled with the plungerthe plunger being provided with a goose neck adapted to receive theupper end of the shoe.

3. In a device of the class described, a

Wheel mounted vehicle; a guide vcarried thereby; a plunger mounted tomove in the guide and including a goose neck engaging the guide tosupport the plunger; means for actuating the plunger to move the gooseneck off the guide; and a wheel and track engaging shoe pivotallyassembled With the plunger, the goose neck being adapted to receive theupper end of the shoe. 1

4. In a device of the classdescribed, a wheel mounted vehicle; a plungercarried thereby; and a wheel and track-engaging shoe pivotallyassembledwith the plunger, the plunger comprising a goose neck adaptedto receive the upper end of theshoe' when the shoe, is tilted, andcomprising afinger engaging the shoe to support the shoe when the shoeis elevated; and means for actu' ating the plunger.

5. Ina device. of the class described, a."

guide; means for actuating the plunger; and a track-engaging shoeassembled With the plunger; the plunger comprising a goose neck adaptedto rest upon the guide to uphold the shoe, and comprising a fingerengaging the shoe to limit the tilting movement of the shoe in onedirection, the goose neck being adapted to ride off the guide and beingadapted to receive the upper end of the shoe When the shoe is tilted outof en- 10 gagement with the finger.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two Witnesses.
